reduce the liability of failure of the parts in` use.

In my novel construction, the structure of the tire equipped portion ofthe wheel or the wheel member comprises four main parts, viz a felloe ortire rim for the outer periphery, a radially corrugated, truncatedconical member or bottomless bowl forming the in'- ner periphery andside pieces oini'ng the edges of the felloe and the edges of the bowl toform a strong annular box or wheel body.

, The tire equipped member or wheel member is mounted. upon the hub'andis held to the hub against lateral movement in either direc-v f tion bybeing assembled between the two flanges of the hub, one of theseyflanges being removable for the purpose.

The smallest diameter of the bottomless 25 bowl is larger than thediameter of the hub A body consequently the wheel member can slidebetween the hub flanges in any radial direction within the'limits ofthedifference of diameters of the hub body and the bowl.

A radially corrugated, truncated, conical disc having an extended 4hubinternally splined is mounted upon the externally splined body of themain hub so that the disc may slide along the body of the main hub. Aspring under partial compression is positioned between one of theflanges of the'main hub and the disc for the purpose of forcing the disctoward the other flange of the main hub.

When the various components of the wheel are assembled the centrifugallyextending projections of the corrugations of the disc engage between thecentrifugally extending` projections of the corrugations of the bowl andvice versa and the overall diameter of the circle bounding or definingthe maximum limitrof the projections of the disc is greater than thediameter of the circle defining the minimum limit of the projections ofthe bowl.

The projections of the disc are thus permanently meshed between theprojections of the bowl and no torque effort or other' effort applied tothe bowl or to the disc can unmesh the one in respect to the other.

disc laterally along the hub body toward the The pressure of the springin forcing thefixed flan causes the concaved corrugations of the disc toslide over the cone faced corrugations of the bowl and so forces thebowl and its wheelmember to a position concentric with the hub andconversely a road shock applied to the wheel member causes a reversal ofthe operation.

oad shocks lcaitise the wheel member to become eccentric to the hub.member by sliding the disc along the hub and compressing the springwhich in turn restores the concentric .i

relation after the road obstruction is passed. Torque applied to the hubis transferred to the disc and so to the bowl of the wheel through theinterlocking relation of the corruga'ions of the disc and bowl and thusrevelves the wheel.

For the purpose of illustrating my invention I have shown in theaccompanying drawings one forni thereof which is at pres.u ent preferredby me, since the same has been foundin practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

Figure l represents a vertical sectional view of a resilient wheel,embodying myinvention, certain of the parts being shown in elevation.

Figure 2 represents a section on line 2-2 Figure l.

`Referring first to Figure l, l designates my novel construction ofresilient wheel, the same comprising a hub 2 having a fixed inner liange3 and a removable outer ange l secured to the outer end of said hub bythe bolts 5, said flange 4ibeing further preyented from rotation uponthe said hub by engagement. of the 'splines G with coacting recesses 7in said flange ii, The flange 4i has a central aperture 8 permittingaccess to the axle nut 9 which secures the hub 2 to the axle 10. 1ldesignates an abutment plate forming an extension to the flange 4A.

16 is a demountable rim secured to the wheel body 12 by thezbolts 17 ortheir equiv- It will be apparent that the wheel body is slidably mountedbetween the .members 3 and 11. 18 designates a radially corrugatedtruncated conical disc having an extended hub 19 breached to slide uponthe splines (i, said disc heilig held in position against the bowl 15 bythe spring 20, said springl 20 being confined between the disc 18 andthe flange 4t. 'Theoutwardly projecting noses 21 of the disc 18 canunder the influence `of ltorque applied to the hub 2 or to the wheelmember 12 assume a'concentric rela- -tion to the inwardly projectingnoses 22 of the zbowl 15 ybut being larger in Vdiameter they cannot.pass the noses 22 of the bowl l5.

.As a Afurther precaution against the complete rotation oit the wheelmember 12 upon the -hub 2 I may employ the studs 23 rigidly fixed Iinlthe wheel member 12 so thattheir inwardly projecting ends 2l engage inslots 25 fashioned in the hub "flange 3. 25* designates a cover attachedto the wheel body l12 bythe bolts 17. A

The operation is as follows TWhen the `various components of the Wheelare assembled, the centrifugally extending projections or thecorrugations of the disc engage between the centripetally extendinvprojections of the corrugations of the bow and vice versa and theoverall diameter of the circle -boundingor defining the maximumlimit'oftlie projections of the disc is greater than the diameter of the`circle defining the minimum limit of theV projections of the bowl.

The rejections of the disc -are thus Vpermanent y meshcd Vbetween ltheprojection of the bowl and no torque effort or otheredort applied to thebowl or to the disccan-unmesh the one in respect to the other.

'The pressure of the spring in fore-ing the disc laterally along lthehub body toward the fixed flange causes the cone-faced corrugations ofthe disc to slide over the cone faced corrugations of the bowl and soforces the bowl and its wheel member to a position concentric with thehub and conversely a road shock applied to the wheel member causes areversal of the operation. y

Road shocks causethe wheel member -to become eXcentric tothe hub memberby slid-.ing the disc along the hub and conipress'ing the spring whichin turn restores the concentric relation when the road obstruction ispassed.

Torque applied to the hubV is transferred to the .disc `and so to thebowl of the wheel through the interlocking Vrelation of the corrugationsof the disc and `bowl and thus revolvesfthe wheel.

It will now be apparent that I have devised a novel and usefulconstruction of re- .embodiment thereof' which has been found inpractice to give satisfactory and reliable results it is to beunderstood that thev same is susceptible of modification in variousparticulars without departing from the spiritor scope of the inventionor sacrificing any of its advantages. j

Having thus describedmy invention, what I claim as .new and desi-re tosecureby Letters Patent, ist- 1.

Ll. In a road Wheel, a hub body having a fixed flange and a removableflange, attached to said hub body by means of coasting splines andbolts, a hollow Wheel having Wheel plates of: ring form united by asubstantially cylindrieal band at their outer edges and by a radiallycorrugated bowl at their inner edges to rotate in relation to the hub,such rotation being limited by the construction to less than the Widthof any one corrugation, and a spring interposed between the radiallyCorrugated dise and the removable hub flange.
